Chinese startup DeepSeek has launched a low-cost AI model with performance comparable to that of OpenAI and Google, sending shockwaves through the U.S. tech sector and causing a sharp drop in U.S. stock markets, with NVIDIA's stock price plummeting in particular. The key to DeepSeek's success lies in its highly efficient data analysis methods, which require far fewer chips than its competitors. This has sparked widespread debate about AI development costs and the effectiveness of U.S. chip sanctions. DeepSeek's open-source strategy has further intensified international AI competition, eliciting varied responses from different countries. Meanwhile, the U.S. is assessing the possibility of tightening export control measures. -- Hosting provided by SoundOn
